ive searched and im still confused.

i have a b16a2 it was originally in my 93 civic dx hatch, now the map sensor plug was in the chassis harness ( fusebox side) and when removing the engine from my new shell, the sensor plus and wiring was in the harness.. im completley confused and need some advice PLEASE... if you need more info let me know, putting motor in a 95 cx btw(edit)

He doesn't know how to get his MAP sensor working/plugged in.

Endo-land

Basically there should have been a plug on your engine harness that you did not use before (hopefully taped it back and not cut it off) that will be your map wiring since in a 95 it is wired to the shock tower plugs. If it was clipped you will need to splice a new connector onto the engine harness. Should be cake.

Endo-land

The only question that may change that would be does your engine have the throttlebody mounted sensor or the firewall mapsensor that only had the vacuum going to the throttlebody.

my map sensor is on the TB on the b16 and it was on the TB on the single cam i took out , so you guys think on the engine harness i have for the b16 it was cut off, since the plug for it is on the chassis harness in my old shell?

Endo-land

Just take the plug off the old car and splice it back on to the engine harness, just make sure you do a good tight job so the sensor does not get bad readings.

sound good endo im gonna grab some grub and then cut open my harness, i hope theres wiring for the map there

egmatt93

o yea it will be sottered and heat shrinked

egmatt93

bad new i just cut open my engine harness and no wiring for the sensor this is

egmatt93

i cut a lil deeper and i found 2 wires just sitting there but im missing a third even if there are for the map, the wires are green with a white stripe and red with a yellow stripe, once again baffled on what i should do...

bump

egmatt93

need some help on what to do here...

should i just pull the map sensor wiring out of the dx and run it to the ecu in the cx?

I'll give you the pinouts, i'm at work now ill post a reply within the hour with the details,


I know how you feel, I did the h22a into a EG and built a wire harness from scratch, so I feel im qualifed to remember where all the wires went in the whole ordeal, gimme a couple and ill give you some assistance.

u would be my hero!

egmatt93

would u or anyone else have the pinout for the map sensor wiring in the engine harness so i can just run it through the engine harness and have it plug n play with the chassis harness?
